Patients were monitored for 18 months, recording implant survival, volumetric bone analysis on CBCT scans, interproximal bone levels, bone sounding, pink esthetic scores, and complications. Prosthetic procedures were also described, including temporary and final restorations. Using the socket shield technique, a cumulative implant survival rate of 95.7% was obtained after 18 months, with a significant but limited reduction in buccal bone thickness (BBT) after implant placement. One implant did not integrate, and two shields were partially exposed. The mean pink esthetic score at 1 year postloading was 12.93 ± 1.22. The study suggests that the socket shield technique can result in a limited reduction of the buccal bone volume, with a high implant survival rate.

Despite various techniques to augment KM, challenges persist in achieving stable, keratinized, and adherent mucosa, especially in the context of significant muscle pull or compromised tissue conditions. This study introduces a novel application of titanium pins for the fixation of free gingival grafts (FGGs) and apically repositioned flaps (APFs) during vestibuloplasty, aiming to overcome important limitations associated with traditional suturing methods, shorten the treatment time, and reduce patient morbidity. Three patients with insufficient KM width presented discomfort during oral hygiene care and showed inflammation around implant restorations and natural teeth. These patients underwent soft tissue augmentation using titanium pins-traditionally used in guided bone regeneration-to stabilize the FGGs and APFs. This method ensures intimate contact between the graft and the periosteum, which facilitates proper graft perfusion and revascularization, minimizes shrinkage, and reduces the risk of graft necrosis. A postoperative follow-up revealed successful graft integration, with minimal shrinkage and increased KM width and depth. The use of titanium pins allowed for reliable fixation in challenging surgical sites where traditional suturing methods were impractical due to the presence of extensive muscle pull and an unstable recipient bed. The application of titanium pins for the fixation of FGGs and APFs during vestibuloplasty provides a promising alternative to traditional suturing techniques, particularly in complex cases where the recipient bed is suboptimal for suturing. This method simplifies and shortens the procedure, offering a predictable outcome with increased mechanical stability and minimal graft shrinkage.

This manuscript describes a dual-layer flap preparation approach that utilizes an external coronally advanced flap (CAF) and an internal trapdoor periosteal flap (TPF) for EMS in the esthetic zone. The external CAF is a split-full-split-thickness flap that allows the gingival margin to be coronally advanced over the cementoenamel junction or prosthetic margin to mitigate any potential gingival recession due to flap retraction or to treat existing gingival recession. The internal TPF is the periosteal elevation of the partial-thickness tissue that remained following the elevation of the external CAF. The internal TPF employs vertical release(s) to obtain adequate access for periapical surgery. Sites treated with this approach healed with no complications, minimal patient discomfort, no facial recession or loss of papilla, and minimal soft tissue scarring.
